Hello, I'm generating PWM signal with the Arduino and outputting it to a 12v transformer to drive a 12v motor. I already have this working but I am trying to control 4 motor sequentially now. So I was planning to assign 4 Arduino pin and have each output to a dedicated transformer but it seems wasteful since the motor don't have to move concurrent. Is there a 12v DEMUX that I can control the pin from Arduino and have the 12v signal from the transformer be output to 4 output instead? If so, what's the chip that I should use? I'm not an electrical engineer and my hobbies are limited to what I can search on this forum and google.
What seems more wasteful to me is buying additional hardware if what you have already is doing the job.
The Arduino can control more than one motor driver. The Arduino does not care if multiple motor drivers share the same power supply. Just hook the power supply to the motor power inputs of all four motor drivers.
Not these motors. These are satellite motor requiring specific powered pwm signals.
Motors are hardware. Please provide a link to information about the motors, or else post more information. Now is the time to also post any additional information that you have.
What is this transformer? Why are you using it? Where did you get the idea, or is it completely original?
What is a "satellite motor"? Is your project currently in orbit?
MC74HC4051A,MC74HC4052A,MC74HC4053A
seems to be able to handle input 12v but at 24mA, Does anyone know that can handle 1A?
Those chips are for small signals, not for motor currents.
Your diagram with the transformer also doesn't make sense.
Driving an inductve load (transformer) from an Arduino pin is dangerous for the pin,
and the secondary 12volt winding wouldn't be able to deliver more than 10mA anyway.
You better start telling us which motors and/or drivers you are using (weblinks).
Maybe then we could advice you what to do.
It currently is an XY problem.
Leo..
Am I going crazy or was that diagram not there originally?
Can't comment on your state of mind, but no, it was added later. If you click on the pencil icon on that post you can see the history.
